calculate the side lengths a and b to two decimal places angle a is 64 angle b is 85 and line ab is 9.3? PLEASE HELP ASAP
qaws [65]
∠C = 180° - (∠A + ∠B) = 180° - (64° + 85°) = 180° - 149° = 31°
AC= \frac{9.3*sin(85)}{sin(31)} = \frac{9.3*0.9962}{0.515} =17,99 \\  \\ BC=\frac{9.3*sin(64)}{sin(31)} = \frac{9.3*0.8988}{0.515} =16,2

State the domain and range of the relation. Determine whether the relation represents a function.
dangina [55]

Answer:

Domain {-2,0,2}

Range {-2,0,2}

Relation is a Function

Step-by-step explanation:

We are given a relation:

{ (-2,-2) , (0,0) , (2,2) }

Domain can be defined as the all possible values of x for a relation. It is considered as a set of all first values of the ordered pairs of a given relation.

Domain of the given relation is {-2,0,2}

Range can be defined as all possible value of y which corresponds to the values of x in the domain. It is considered as a set of all second values of the ordered pairs of a given relation.

Range of the given relation is {-2,0,2}

A relation is a function if only there is one value of y for each value of x. If in the set of ordered pair of the relation, the value of x gets repeated, then the relation is not a function.

As no values of x are getting repeated, the relation is a function.

Expand<br> c(3c - 3)<br> I need help on this
Rudik [331]

\\ \sf\longmapsto c(3c-3)

Apply distributive law

  • a(b-d)=ab-ad

\\ \sf\longmapsto 3c(c)-3(c)

\\ \sf\longmapsto 3c^2-3c

We can still take common

\\ \sf\longmapsto 3c(c-1)

Please Help!!!
Mkey [24]
The equation looks like this:

26=x*3.5+8.50

where x is the number of pen you bought.

We solve it like this:
first, we subtract 8.50 from both sides:

17.50 =3.5*x

now we divide both sides by 3.5:
5=x

so you purchased 5 pens.
